The use of a FRP or plastic type material for headliner and side walls has been used in our coaches for at least 20 years+. It provides a durable material when used for headliner replacement and sidewalls and is impervious to water leaks is easy to clean up and looks nice. It has one major drawback and that is noise control. As for Ken H it will not be an issue, but for others the reflective sound can be quite harsh, both in going down the road with road noise and with voice conversation and TV and Music. I have know several GMC’ers who’s wives that have headliner material added to reduce the noise. Just my personal observation, others results may vary!
